Max Weber Code A42, CSS Tel: (850)235-5445 Email: WeberMD@ncsc.navy.mil 30 January 2001 NAVAL SURFACE WARFARE CENTER SHIP ROLL STIMULATION SYSTEM (SRSS) STATUS

Slide2: 

Ship Roll Stimulator System (SRSS) Objective Induce accurate, repeatable T-ACS ship roll, up to + 3 degrees, dockside and at anchor. Provide a realistic, cost effective crane operator training facility and a test platform to validate future R&D crane improvements.

Review of SRSS Requirements: 

Review of SRSS Requirements Develop one system for T-ACS 5 to produce up to + 3 degrees ship roll Conform to available ship space Removable (or disengaged) within a two day time frame ABS and Coast Guard approved system Safe to operate Controllable within period variation due to ship loading
